'''Jitter point arrays for 2,3,4,8,15,24 and 66 jitters.'''

# The arrays are named j2, j3, etc. Each element in the array has the form,for example, j8[0].x and j8[0].y
# Values are floating point in the range -.5 < x < .5, -.5 < y < .5, and have a gaussian distribution around the origin.
# Use these to do model jittering for scene anti-aliasing and view volume jittering for depth of field effects.
# Use in conjunction with the accwindow() routine.
